IMPROVEMENT IN FO'RGING, SHEARING, AND PUNCHING DEVICES.

Specilication forming part of Letters Patent No. 55,263, dated June 5,1866.

To all whom it may concern:

Be it known that I, JAMES E. EMERSON, of Trenton, in the county ofMercer and State of New Jersey, have invented certain new and usefulImprovements in Anvils; and I do hereby declare the following to be sucha full and exact description thereof as will enable any one skilledinthe working of iron and steel to make and' use the same, referencebeing` had to the annexed drawings, making part of this specilication,in which- Figure 1 is a longitudinal vert-ical section through myimproved anvil, and Fig. 2 is a transverse vertical section on the lineI I ofV Fig. l. l

. The nature of lny improvements consists in combining with an anvil forforging and other smithing purposes a power punch or shears, or bothpunch and shears, for convenience in cutting metals.

A A is the anvil, constructed of the generally-adopted form modified tosuit my improvements. B is a shaft having a pinion, C, keyed upon it,and having a square or other shaped head on each end, to be received ina corresponding opening in the end of a lever or wrench, D, which may beapplied to either end of the shaft B.

rlhe pinion C makes in to the toothed segment E on the long end of thelever F, having its fulcrum at G. The short end H of the lever is also atoothed segment having its center at G, and its teeth mesh into those ofthe rack K, moving vertically in guiding-recesses and carrying at itslower end a punch L, which may be of any desired form, to act as aslotter or a gummer for saws, or for any punching purpose, or it may befor a former.

The die L for the punch is in a block let into a groove in the bed ofthe anvil, dovetailed on one side and secured by a key, M, drivenbetween the other side of the groove and the block. The sides of thegroove are made parallel, while the block is made wider at one end thanat the other, and the key has a correspondin g taper.

The metal after being punched is cleared from the punch by a device, 0,common to punching-machines, consisting of a fork having its prongshorizontal and one on each side of that punch a short distance above thedie, and firmly secured by a set-screw to the end of the anvil.

One of the blades, N, of the shears N N is secured in a suitable mannerto one side of the recess which contains the lever F in the body oftheanvil, and the other blade, N', is secured to at projection from theshort end of the lever F, so that its edge shall form an angle with thatof N in a manner common to shears for cutting` metal.

When the lever or wrench D is vibrated the pinion U on the shaft Bcauses the lever F to vibrate and give motion 'to the punch with greatpower by means of the segment H and rack K. The same movement of theleverwrench D also causes the shears to perform their work throughthemedia of the pinion and segment E in the lever F. The workman at theanvil thus has no occasion to lose time and heat in seeking to havethese offices performed oftentimes at some distance from the forge.

Having thusfully described my improvements, whatI claim as new therein,and desire to secure by Letters Patent, is-

An anvil, shears, and ,punching-machine, arranged, combined, andoperating substantially in the manner and for the purpose set forth. Y
